1277609 Drying polymers with microwaves ESSO RESEARCH & ENG CO 5 Dec 1969 [23 Dec 1968] 59422/69 Addition to 1226988 Heading F4G [Also in Division H5] The method of drying non-polour polymers, as described in the parent Specification is modified by replacing the belt conveyor by one or more vibrating acrobating microwave resonating cavities, which convey the polymer through the cavity when inclined to the horizontal. The microwave frequency falls within the range 600 Fo 40,000 MHz. |
